Free space on both sides of the bearing

To prevent interference between rotating bearing parts and stationary machine parts, free space (Ca) should be provided as indicated in (fig. 1).
The requisite width of the free space Ca depends on:
  • the actual misalignment
  • lubricant space requirements
That requisite free space should be at least 20 times the minimum value of the radial internal clearance in the unmounted bearing (table 1 or table 2).
For additional information, contact the SKF application engineering service.
